Formal vs informal: which synonym fits?
Formal writing: robust, mighty, resilient, durable, forceful, potent, hardy. Use these in essays, reports, business emails, and formal stories.
Everyday writing: powerful, sturdy, solid, muscular. These work in most sentences and are safe for blogs, school work, and general writing.
Casual speech and dialogue: tough. These sound natural when a character is speaking, but they can sound too informal in a formal essay.
Example sentences
- The powerful engine pulled the heavy train up the hill.
- She built a sturdy table that will last for years.
- His resilient spirit helped him recover after the injury.
- The lawyer made a forceful argument that convinced the jury.
Notice how the same feeling changes when you change the word: a formal synonym makes a sentence sound serious, a casual synonym makes it sound like natural speech, and a neutral synonym works in both.
How to avoid repeating strong
Do not use strong in every sentence. Rotate through the table above: use one synonym in the first sentence, a different one later, and keep strong itself for the most important moment. That way the writing stays clear without sounding repetitive.
